l Application filed. February .20, 1883. (No model.) i

To all whom it may concern: Y

Be it known that I, JULIUs A. SPENCER, of Dwight, in Livingston county, and State of Illinois, haveinvented certain new and useful Improvements in Baling-Presses, the construction and operation of which I will proceed to explain, reference being had to the annexed drawingsand the letters and figures thereon, in.which -Letters Patent dated August 22, 1882, No.

262,992, were issued to this applicant.

The first in'order of the improvements in this machine is in the device for reciprocating the plunger P. The rear of the plunger 1? is hinged to the end of the toggle-joint, consisting of the two levers P and P jointed together about two-thirds the way back from the plunger.

upward and attaches at its upper end to the beam B, supported by the beams B and B The drive-chain c, which comes from the power and passes over the pulley R, and runs horizontally forward, is provided at that end with the pulley-block R, that travels on the chain c. When the power is applied to the chain c it will pull on chain c and carry it backward, by means of which the toggle-joint P and P is carried upward and draws the plunger 1? back out of the bale-chamber, and all the parts, when the plunger is back, are

in the position shown by the dotted lines in Fig. 4..

It will be seen that the joint S, where the rear end of the toggle hinges, is on a plane below the center of the plunger P. When the parts are in the position shown in Fig. 4, the plunger is forward at its farthermost point against the bale in the bale-chamber, and the toggle-joint lies so thejoint J is depressed to The rear end of the leverP is hinged to the frame A at S. A chain, c, attaches to the joint J of the toggle, and extends I a line a little below the points where the lever P is hinged to the plunger, and S,.where lever P is hinged to the frame, and the joint J rests on the post J. When in such position chain 0 is nearly straight, and when chain 0 begins to pull on it, it will pull upward on the toggle-jointwith great force to raise the joint above itscenter, when the elasticity of the bale will start the plunger back rapidly and throw the toggle-joint up, so the plunger will move back at a greater speed than the chain 0 travels.

hay into balesthe plunger P is driven forward into the bale-chamber against the material to be baled by means of the chain m, which comes from the power over pulley n, and attaches to the under side of the knee-joint of the toggle P I, as shown in Fig. 4. When the power pulls on said chain at the kneeplunger P forward, as shown in said figure. The power by means of which chains 0 and m are operated may be so constructed that it pulls alternately on said chains, but not on both at the same time. Chain m is used to pull down on the knee or toggle jointto throw the plunger forward, while chains 0 and o are for the purpose of returning the plunger by lifting up on the knee or togglejoint to which chain c attaches, as before stated.

Any power may be used that will pull alternately on chains m and c, and as the power is no part of this invention, no further description of it is deemed to be necessary. M

It is obvious that as the lever P approaches a perpendicular line it opens the toggle-joint easier, until at last its own weightcarries the plunger back as far as is necessary, as shown by the dotted lines in Fig. at.

Hinging the toggle-joint on the frame at S on a plane below the center of the plunger P, where its opposite end is hinged, partially rethe toggle-joint down to force the plunger forward, as thetendency of the toggle so arranged is to force the plunger more directly forward without frictional contact with any side of the bale-chamber to any extent. Another object III the operation of baling or pressing the lieves the plunger from friction on the bottom of the bale-chamber, when the chain m pulls 9 joint is straightened, and thereby'presses the I in so hinging the toggle at S, as stated, is that when the, roof of the bale-chamber is loosened the force of the plunger against the bale will raise thebale alittle off the floor, so that when the plunger recedes from the bale it is loose and can be readily removed from the balechamber.

Another improvement consists in the means for opening the feed-door D at the side of the feed-chamber when the plunger returns. This is accomplished inthe following manner: An arm, L, is pivoted at its lower end in the frame A, as shown in Fig. 4. To its upper is attached the cord to, which passes over the pulley R in the outer end of the beam 11, and passes thence down and attaches to the weight M, which slides up and down in the ways a a When the toggle moves upward and backward -the pin 0 at the joint J (shown more clearly in Fig. 1) comes in contact with the arm L and carries it backward between the beams 41 0 until it is in the position shown by the dotted lines in Fig. 4, which will elevate the weight a so the turned-up or bent end of the rod 0 will fall into the notch on the side of the weight a (shown at b in Fig. 3.) This slackens the cord to, which connects the weight a withthe latch e on the side of the door D, so the said door may be closed by the operator. Said door remains closed. until the plunger is moved forward to press the bale, and

far enough so the bale is carried past the door I), when the pinp on the side of the plunger meets the opposite bent end of the rod a, as shown by the dotted lines in Fig.3, hearing it down and releasing the other end from the notch in theweight 0. which permits the weight a to fall, and, by means of its attachment with the door D by the cord to, pulls back the latch e andpulls thedoor D open, thussaving the labor of having to open it by hand. The dotted lines in Fig. 2 show the position of the doorD when open. The rod on has an. arm, a, attached to its side next the weight 0?, to cause its bent end I) to bear against the weight a so as to readily fall into the notch of the weight.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows, to wit:

1. The combination of the toggle-jointP P vertical chain c, and drive-chain 0, having the pulley It to roll on chain c, all adapted tooperate as and for the purpose set forth.

2. The combination of the vertical arm L, pivoted at the lower end in the frame A, cord to, weight (4 having a notch in its side for the reception of the bent rod a, bent rod a, hav

ing its inner end bent to engage with the trippin p on the plunger P and its outer end bent to fall in the notch of the weight a pin 2, and cord to, all adapted to operate as and for, the

- purpose set forth.

3. In a baling-press, the toggle-joint P and P having its opposite end from the plunger hinged to the frame A on a plane below the point of its attachment to the plunger, as and for the purpose set forth.
